I have found that I can combine'an lin-line spring securing means'for the connection "in coordination witha snap 'securing means,` and thus y obtain a combination of securing means so inter-related as to rinsure'-afmo're'positive means to maintain the 'component members together', and obtain a connector that can be quickly conforce.

It is therefore a'primary 'object ofmy'invennected or separated with a smallipredetermined tion to provide a' connector ofthe llongitudinal displaced type having an improved means for securing together the component' parts of a'c'onnector an'dwhich will? afford a high L'degree of 'electrical and mechanical efficiency.

l 'It is a further A objectof' my invention to provide in a longitudinally- 'displaced-#type of "connector; a 'spring means" for 'securing thev connector partstogetherand plurality of longitudinally spaced Contact points to bias the spring means ner.

Still other objects of my invention 'are to provide a spring male connector part having detent securing means at one end; to provideaftwo vpiece separable connector that 'can be'stamped' or otherwise formedv of sheet metal, whichican be manufactured economically, one ofthepeces -A Vhaving a tubular'end to which may be` secured a conductor; to provide v'af-separable connector wherein one of the contact members is wedged `intoposition in a line offset from the face of "the other contact-member; 'and'to provide a connector having superior electrical and mechanical efficiency.

I accomplish these and other objects and obtain my new results as will be apparent from the device described in the following specification, particularly pointed out in the claims, and illustrated in the accompanying drawing, in whichto support thev parts together ina ,positivemam 35.

AA shoulder I9 is formed on the lug portion i4 to abut the outer edge of the female portion and limit the inward movement of the tongue portion when inserted.

The female member l2 may be made of hard copper stamped from sheet material forming a blank as illustrated in Fig. 4. The blank is constructed with three sets of tab portions of varying `l3 when inserted.'` e

A portion of the base of 'the channel 3 3 is i To form the finished female..rneinberthe.endjr My device makes possible a quick disconnect connector having with it a novel means to secure the parts together to insure anY improved electrical and mechanical connection. By constructing a hollow body portion in one end of the female member and a dimple spaced therefrom,

I can Wedge the'fspringy tongue of ,the male porl .prw'ide'a .connection comprising two parts which portions 2| and 22 of the blank are rounded to L form the barrel portion 30 as shown in Figures 1, 2, 7 and 8 having a shroudj?orti'onv 3l. .fThefl bared end of conductor 32 is inserted and'crimped or otherwise secured within the barrel portion,

with the conductor insulationaccommodated Within the shroud portion. The end portions 2 l and 22 may be of a width to form the barrel by overlapping. Central tab portions25 and 2B are bent upwardly' forming a U-shaped channel 33, as shown in Fig. to guide the movement of the male portion I3 and to restrict side-wise movement. The end tabrportions 23 and' 24 are bent over and around to form a substantially rectangu- 'lar retaining body or enclosure"34,' as shown in Fig. 6, to enclose and reta'n the tengueportion struck up from the bottom to form a dimpleor detent 35 extending into the channel Vwhich dim- Vple engages one .of thefgrooves I6 of the tongue portieri and by'exur'e'secures the male member .within the female member, as shown in Figs. 2-- l'and 5 depending Yon which position the tongue is inserted into the`fexnale member.v The dimple may be formed in the'."connector while in the form of the blank as shownin Fig. 4.

The tongue portion I3 wheninserted, engages the female member `|2` atsubStantially three points, A, B and C in a line offset from'the base of thev female member, insuring a good wiping surface as it is inserted to form an efficient electrical. connection. The'p'oint A is the lower in- .ner edge ofthe Vretainingbody 34 at the outer end; the point lB'is'the upper inner edge of the retaining body 'attire inner end; and V,the Vpoint C is the'top of the dimple 35. The tongue being resilient 'conforms'toj the shape of the female memberat the three points of engagement and is wedged into and retained in position by spring pressure; the dimple engaging the groove forming a supplemental securing means. However a p redetermined pull will quickly separate the connector parts when necessary, and the connection may be quickly made by pushing one within, the

other.

In Figs. '7` and 8 is shown av multiplel arrangement of connectors mounted to a terminalboard 36. l.This construction differs from that disclosed in Figs. l-6 inclusive, in the details of the male l member 3l which is provided with four integrally spaced tongue portions'38, 39, 4U and 4| for each of the connectors and is secured to the terminal board by the central body or lug portionw42 by bolts 43.V The female members may instead be integrally formed.
